Aortic Regurgitation

Aortic regurgitation is a disease of the aortic valve Pathophysiology 1) progressive deterioration of aortic valve or aortic root 2) allows blood to leak back into left ventricle during diastole 3) results in chronic left ventricle volume overload and left ventricular hypertrophy Causes of aortic regurgitation 4) chronic rheumatic heart disease (most common) 5) infective endocarditis 6) Marfan’s disease 7) ankylosing spondylitis 8) congenital subaortic membranous stenosis 9) condition is well tolerated until late in course Signs and Symptoms 1) high-pitched decrescendo blowing murmur in diastole best heard at third left sternal border 2) Corrigan’s pulse (“water hammer” or bounding pulse) 3) Musset’s sign (bobbing of head during systole) 4) Quincke’s pulse (blushing of nail bed when nail is lifted upward 5) pulsating uvula 6) Austin Flint murmur (regurgitant stream hits anterior leaflet of mitral valve, causing vibration) 7) widened pulse pressure (increased stroke volume and loss of blood during diastole) 8) systolic pressure reaching 300 mm Hg 9) Traube’s sing (“pistol shot” over femoral artery) 10) Duroziez’s sign (“to and fro” murmur over femoar artery if slightly compresse 11) exertional dyspnea (usual presenting symptom)     The post Aortic Regurgitation appeared first on InsideSurgery Medical Information Blog.
